The outage seems to be global, with people reporting trouble connecting to Messenger in Western Europe especially, but challenges in California and Washington/British Columbia as well.

Messenger is generally reliable, but has had more issues recently, with four outages in September alone.

The recent update, a "Remove for Everyone" feature, give users 10 minutes to unsend or delete a sent message. It's intended to save you from embarrassment or trouble for an ill-advised message, and it is just in the process of getting rolled out globally.

(Initially, on CEO Mark Zuckerberg could use it.)

There's no word yet on what caused the issue, or if the new feature has anything to do with it.

While Messenger is down, WhatsApp, Facebook's other big messaging platform, is chugging along just fine.

Messenger has over 1.3 billion monthly active users, so even a short outage can affect a lot of people. WhatsApp, however, is slightly bigger: 1.5 billion monthly average users.
